How does the QC team test and validate Li-ion products?
After selecting top-notch factories and products, the QC team conducts performance tests to estimate product capabilities, enabling comparisons to determine Li-ion products projects feasibility.
The QC team chooses various products from different factories meticulously to test the performance and record the parameters and condition when using.
Li-ion drills and wrenches have to meet the basic requirements of 10 cycles and every product has to meet its machine working performance requirements.
Machine working performance requirements are specified for each product:
Brushless Impact Drill:
For machine assessment: Use a flat drill bit of ø25 to bore through hardwood boards exceeding 40mm in thickness. Using one machine with a 4.0AH dual battery continuously for one cycle, followed by a 20-30 minute rest period. The machine should work normally and every function should work well after completing 10 cycles.
Monitor parameters: Voltage, current, speed, torque, etc. before, during, after the forward and reverse movement.
Record number: Record the number of holes drilled per single battery.
Brushless Wrench - Requirements for 300N.M/500N.M Models:
For machine assessment: Use one machine with 4.0AH dual battery to tighten screws/bolts of size M20 or above (using 32/36 sockets) as one cycle (8.0AH). Tightening sequence: 3-5 seconds for forward and reverse each. After one cycle, allow a 20-30 minute rest. The machine should work normally and every function should work well after completing 10 cycles, with torque reduction not exceeding 10%.
Monitor parameters: Voltage, current, speed, torque, etc. before, during, after the forward and reverse movement.
The QC team meticulously documents various facets during testing processes.
Data for each machine both during and post-testing is recorded. Nuances of machine performance are captured. The strengths and weaknesses of every machine are meticulously cataloged. These evaluations classify products into three ranks, distinguishing varying levels of quality. The QC team derives insightful conclusions, pinpointing crucial areas of attention, key technical aspects, and challenging technical points.
This testing process isn't merely evaluative; it serves to delineate precise product requirements, laying the groundwork for prototype development by providing a thorough understanding of product intricacies and demands.
